Can I list something to be scheduled later and pay for 6p scheduling fee, then later (before the listing is due to start) go back and amend the listing to start immediately and have any 6p refunded, without incurring any extra fees? I wouldn't pay to list it twice, would I? (once with the scheduling fee and once without)
I know it seems an odd way to do things but for reasons too long and boring to go into, this is how I find it easiest to list stuff!
